OL 9 cron configuration files directory must be group-owned by root.

Service configuration files enable or disable features of their respective services that if configured incorrectly can lead to insecure and vulnerable configurations; therefore, service configuration files should be owned by the correct group to prevent unauthorized changes.

Verify that OL 9 configures group ownership of all cron configuration files with the following command:

$ stat -c "%G %n" /etc/cron* root /etc/cron.d root /etc/cron.daily root /etc/cron.deny root /etc/cron.hourly root /etc/cron.monthly root /etc/crontab root /etc/cron.weekly

If any crontab is not group owned by root, this is a finding.

Configure any cron configuration not group-owned by root with the following command:

$ sudo chgrp root [cron config file]
